CONTOURING DEVICE F833, SHEET MATERIAL.

To all whom it may concern Be it known that we, THOMAS Room: and PERCY WILLIAM DAVIS ROCHE, subjects of the King of England, residing at Leicester, in the county of Leicester, England, have invented certain new and useful Improvements in Contouring Devices for Sheet Material, of which the following is a specification.

This invention relates to a contouringdevice for sheet material. It is for the purpose of enabling related different sizes or grades of patterns, for instance the patterns of boot or shoe uppers, soles or insoles, to be produced from a standard pattern or templet in a more certain and simple manner than heretofore. This is accomplished by the provision of simple means to locate points within or without the contour of an original pattern, which shall conform to the contours of the other related grades of pattern required; said means obviate the need for reliance on individual judgment and calculation or on the expensive and complex pantographic and other mechanical copyingdevices heretofore employed.

Broadly speaking the invention comprises a support or base-piece, pluralities of correlated movable gaging-devices borne by the base-piece, operative connections to maintain the said correlation which consists of a pre-determined geometrical relationship be tween the correlated gagingdevices of each plurality, and constraining means to maintain the gaging devices in predetermined planes relatively to the basepiece while they are in their operative positions. The correlated movable gaging-devices are so disposed in relation to the operative connections aforesaid that if in any said plurality one of the correlated gaging-devices be brought up to a point in the contour of a standard or primary pattern, say a contour mark or the edge of a templet the other gaging-device that cooperates with it will be found in such a direction in relation to it and at such a distance from it as to serve to indicate the corresponding point in the contour of the different or related pattern, which may be larger or smaller than the original. A series of such gaging devices can thus be used toindicate by a series of points the whole of a contour.

Specification of Letters Patent.

Application filed April 27, 1907.

Patented June 30, 191 Serial No. 270,541

Preferably the correlated movable gagingdevices are combined with constraining means which maintain. them in pre-determined paths relatively to the base-piece.

A contouring-device according to the present invention is illustrated in the accompanying drawings, wherein Figure l is a plan of a complete contour- 1ng-device; Fig. 2 is a section of part of Fig. 1 on the line 2-2, Fig. 1; Fig. '3 is a perspective view of one of the slide members hereinafter referred to, removed from Fig. 1, and having its central portionbroken out to show the form of its transverse section; Fig. 4 is a plan and Fig. 5 a transverse section of a construction of slide-member alternative to that which is illustrated in Fig. 3; Fig. 6 is a plan of a portion of a device such as is shown in Fig. 1, but having a slide-member carrying more than one set of gaging-devices and constituting an alternative to the construction of slide-member illustrated by Fig. 4c; Fig. 7 is an end view of Fig. 6, and Fig. 8 is a view similar to Fig. 2, but drawn to a larger scale and showing yet another construction of slide member.

Like reference letters indicate the same parts throughout the drawings.

lVith reference first to Figs. 1, 2 and 3, the contouringd vice comprises a baseplate or base-piece A. It approximates in shape to an enlarged boot-upper. It is preferably made of metal. The correlated movable gaging-devices hereinbefore referred to are constituted in this example by pins D and the portions of slice members C in which are holes B. Each pin D is on a slideunember C, on which it is located in the desired relationship to each one of the holes E in the same slide-member, said holes being each adapted to permit of the passage of a point of a pricker through the slide member. Any one hole E in any one slider C is made therein at a pre-determined distance from the pin D of that slider, so that said hole and the pin are correlated with eons aining means by which in this ex- 11ml? rained in prodetermined planes relatively to the base-piece Bi consist of guides constituted by the sides oi slots A formed in the margin of the baseplate A and more or less converging to the middle thereof. 'lhese slots receive each a slide-member C. l ath slot has a central flange A upon each sine at it as may be seen from the section Fig. 2 and the slide member shown in Fig. 3 engages with the slot, being recessed or grooved as at A so as to grip frictionally the sides of the slot in which nevertheless it is freely movable upon the exertion of a moderate effort.

in use the apparatus 01' Figs. 1, 2 and 3 is placed upon the material out of which the retp'iired pattern is to be cut, and the stand,- ard pattern or templet P (see chain lines Fig. 1) is placed approximately centrally on top oi? the base-piece A. The slide-members (l are then adjusted to bring the pins D 'herem'i into contact with the margin of the standard pattern, which. may then if necessary be removed. lVhen smaller sizes than the standard pattern are to be made, it will be necessary to remove the pattern. By pricking through the guide holes E, marks may be made on the material beneath that will indicate the contour of the other grade or grades of related pattern desired.

It more than one scale of gradations is desired, say for instance, for quarter and transfer grades, the slide-members may be made as shown in Figs. t and 5, wherein the member has one pin D, but two sets ll E of guide holes, each set di'lli'erently spaced, the holes E serving for the one scale and the holes E for the other scale.

The slide member of Figs. a and 5 is of ection. The cross section of the slot in which this slide is intended to work will be correspondingly T shaped and the slide will be adjustable therein being clamped when so adjusted by means of the knurled nut C mounted upon the screw C attached to the slide.

The slide member of Figs. 6 and 7 has the holes of one scale at one of its ends, and the holes E of another scale at its opposite end. To each set of holes is appropriated its own pin D and D""respectively.

The further alternative construction of slidcanember illustrated in Fig. 8 is compound. That is to say it comprises a bar C sliding in a groove A in the surface of the base-plate A. From the bar 0 a threaded stud G extends upward through a slot in the top oi the groove A and through a washer C A nut C encircling and in screw-threaded engagement with the stud above the washer serves not only to keep the bar in its place and to maintain suflicient friction between the contiguous surfaces of the bar C washer C and base-piece A to prevent the accidental movement of the slide member, but also serves if it be sulliciently tightened, to constitute a locking device for the slide member which will maintain it in any position in the groove to which it may be adjusted.

The shape of the base-piece A. may be modified if desired to correspond with the shape of the pattern for which it is intended to most commonly employ it.

rrl'though in the example hereinbefore de scribed the correlation of one gaging device pthe pin D) to the cooperating gaging device the portion of a slide member that has one of the holes E in it) is secured by the use of a rigid member bearing both said devices,

and. is permanent and invariable, this correlation forming one of the advantages of this invention is not of necessity invariable. It is only necessary that it be definite in any given situation of the correlated devices. llloreover, although the maintenance of the correlated gaging-devices in predetermined planes relatively to the base-piece while they are in their operative positions is secured by supporting them on slide members C in the guides A in the base-piece A such maintenance, which is another of the advantages of this invention need not be secured by this pz-irticular means.

lVhat we claim as our invention and desire to secure by Letters Patent is 1. A device for laying out from a stand ard pattern a pattern of different size but of related contour having in combination asupport for the standard pattern, members slidable with respect to said support, said members being movable in fixed paths which converge toward the central portion of said support, and stops on said sliding members arranged when said members are moved toward said central portion to contact with the edge of said standard pattern, means being provided in fixed relation to said stops for permitting the laying out of a pattern the contour of which differs from but bears a desired relation to that of said standard pattern.

2. In a contouring device, a plate having slideways in its edge portion, slides for each slideway having means to contact with the edge of a pattern to locate the slides relatively to a point on the pattern, said slides being constructed to locatecorresponding points in similar patterns of difierent sizes.

3. In a contouring device, a plate having slideways in its edge portion, slides in said slideway having means to position the slides with definite relation to a point in one contour and other means upon the slides to indicate the direction and distance of a corresponding point in a similar contour of larger size.

4. In a contouring device, a plate having slideways in its edge portion, slides in said names to this specification in the presence of slideways having means to position the two subscribing Witnesses.

slides with definite relation to a point in one v contour and other means upon the slides to DAVIS ROCHE indicate the direction and distance of a corresponding point in a similar contour of WVitnesses: smaller size. ARTHUR ERNEST JEROME,
